Explain primary, secondary, tertiary endocrine gland disease
1- issue with gland itself
2-issue with adenohypophysis
3-issue with hypothalamus
What is panhypopituitiarism
Decreased production of all anterior pituitary hormones
Causes of panhypo
ACQUIRED: Radiation Infection Traumatic brain injury Infiltrative disease Pituitary apoplexy Tumour Inflammatory Peri-partum infarction
more rare- congenital
What causes congenital panhypopituitarism
Deficient in?
Appearance in MRI
Appearance of individuals
3 types of panhypopituitarism
Usually due to mutations of TF genes for Adenhypophyis
GH and at least 1 more anterior pituitary hormone
